Is the alternator putting out a charging current when running? Measured at alternator then at battery. If no at alternator, replace alternator if high mileage, if low mileage replace regulator. The part the harness plugs into.

If yes at alternator and no at battery, check for continuity across ammeter and check the voltmeter for a short. The ammeter should read essentially zero ohms and the voltmeter should read about 15,000 to 40,000 ohms when measured with an analog ohm meter.

If those check okay, check for a wiring fault or a blown fuse on the power distribution block or a broken fusible link. Fusible links can be checked by gentle tension on them, those that have failed will pull apart.

SOURCE: Rapid battery discharge

Battery discharge when connected is a regular fault when there are too many electronics connected some of them directly active even when the main switch is off. these can be the clock, the stereo system, the power amp, the remote controller, the auto lock, auto start or any other accessories. You will need to carefully go about to identify with the aid of a good ammeter. Disconnect the main battery terminal and recconnect it in series with the ammeter. If there is a leak in the system it will show up as a good reading . Usually a reading less than few milli amps can be ignored but if the current drain is high then carefully disconnect each of the acessories which is present in the car either byt disconnection of fuse or main wire to device. Once the reading drops to a very low level on discoonection of a particular device, you have the culprit in hand. Keeping this circuit disconnected and check out after two days but your batterry must be in trim condition ( not drained earlier). Hope this helps you out. Good day

sounds as though you have a bad alternator or a loose alternator belt and the battery is not being charged. while the car is running - check the voltage from the alternator and make sure it is about 13.4 volts DC.

95 Cadillac sts will not hold charge,new battery new alternator?


What's the voltage reading at the battery with the engine running ? 13 to 14.1 volts ? If not, it's not charging .Sounds to me like it's not charging ! Is there battery voltage at the heavier gage wire on the back of the alternator ? Does the battery symbol light on the dash work ?

Won't start lights on the dash flashing on and off no management light on


Sounds like the battery or the alternator
Usually has to do with the voltage regulator in the alternator.
That tells it where to put the power and how much output to put.
If the voltage starts to fail it will put the power to the most important parts which is the engine and it will make your lights flicker.

New altanator. ..new battery..battery still not taking charge...please help


Go to Autozone and use their free tester to find out whether your battery or your alternator is not working. A new battery should definitely take a charge and hold it unless the alternator is not charging at the right voltage (usually at least 14 volts). If the voltage controller on the alternator is not putting out right voltage, say 10 volts or so, then the battery will never charge because the charging minimum voltage is 12V. If you have access to a plug in battery charger try that and see if the battery is taking the charge. Sometimes new batteries can be destroyed in a few days if you do a COMPLETE discharge and try to charge it back. Those lead plates are real thin and a complete discharge will warp the plates and they will short circuit and make the battery useless. Autozone will be able to tell you if the battery is good or not and the same with the alternator.

I've also changed the battery and alternator my


you don`t say what year and model this is. if you have a system charging at 16 volts, then you know its over charging. are you checking this with a volt meter independent of the car as the meter in the dash maybe wrong. if its over charging with an independent gage it could be the computer as it controls the ground circuit to cause the system to charge and discharge to keep the charging rate within specs. the flickering is a result of the over charging.

1996 lerado grand cheroke jeep, battery gauge went to to negative, no power new won;t stay running new battery, alternator checks out good any ideas


First check your battery get a cheap digital volt meter. Free at Harbor freight with a purchase. Fully charged battery 12.6 volts Not 12.5 or 4 or 3. With the volt meter set on DC volts touch the battery and have someone start the car if the meter shows high 13.5 to 14.7 the alternator is ok if it is less replace. If you have a dead short take out every fuse and relay from the black box under hood by the battery. Remember where they go and plug them one at a time until the discharge hits and at least you will know what circuit it is.They also sell about 20 dollars a plastic meter you hold over the positive battery cable to see if the starter is drawing to much power A battery open-circuit voltage test will show the approximate state-of-charge of a battery. This test can be used if no other battery tester is available.

Before proceeding with this test, completely charge the battery. Refer to Standard Procedures for the proper battery charging procedures.
  1. Before measuring the open-circuit voltage, the surface charge must be removed from the battery. Turn on the headlamps for fifteen seconds , then allow up to five minutes for the battery voltage to stabilize.
  2. Disconnect and isolate both battery cables, negative cable first.

118345962 Testing Open Circuit Voltage

  1. Using a voltmeter connected to the battery posts (see the instructions provided by the manufacturer of the voltmeter), measure the open-circuit voltage.

118345963
See the Open-Circuit Voltage Table. This voltage reading will indicate the battery state-of-charge, but will not reveal its cranking capacity. If a battery has an open-circuit voltage reading of 12.4 volts or greater , it may be tested to reveal its cranking capacity. Refer to Standard Procedures for the proper Micro 420 battery test procedures.

2002 mercury montaineer , battery light comes on , they gages shut down couple minutes after then the truck acts like it gonna shut off....when getting a jump, the truck fires right up, couple minutes...


Your battery is definitely low. First clean the terminals on the battery and the inside of the terminal rings on the wires. If you have a slow charger put it on that overnight and see if it holds a charge. If it still keeps depleting or doesn't charge overnight then either your battery or your alternator are done....possibly both. So take the battery to have it load tested. Most places that sell them can test them. If the battery is done replace it then test the battery with a volt meter. If the old battery is still good put it back in the vehicle and test the voltage with a volt meter. With the engine off the voltage should read 12 volts (once its fully charged or if its new) with the engine running it should read around 14 volts. If it is way higher than that or it doesn't go up at all your alternator requires replacing. Alternators are fairly easy to replace but if you don't feel comfortable with that take it in to a mechanic.

Will not hold charge


Probably a bad battery. Bring it to a parts store for a free check of the charging system and battery. They can tell you what the problem is. Either the battery is bad, or the alternator is not charging.

New battery. No dash lights or and will not turn over to start


were the cables really corroded sometimes even cleaning them isnt enough due to corrosion in the cable check for voltage at batt and at starter with testlight or volt meter
